Application Build Error #6

Hi Christian,

I wonder if this package has been used on Meteor version 1.8.0.1?

I'm receiving the same error output on releases, 0.1.1 and 0.1.0.

Have successfully added the package to my app but just running into an error with the 'split' property. Could offer any assistance at all, error output below : -

=> Started proxy.
=> Started MongoDB.
I20190103-14:28:41.593(0)? 9

Any help would be much appreciated.

Thanks,

I haven't tried on meteor 1.8 yet, but the error is a well known issue: you have probably not sourced your ROS environment before starting meteor. The split that is failing is on the content of an environment variable that is set by ROS's setup.[bash|sh|zsh]. Can you try again after sourcing that file in the terminal where you start meteor? (usually source /opt/ros/kinetic/setup.bash) Please let me know if that fixes it.

Ah, that's great, thank you, that works. I hadn't sourced the ROS environment into the same terminal session as the Meteor app.

I'm just running into an error, when calling ROS inside my (/server/main.js with the line : -

const ros = ROS();

I seem to be getting an unresolved promise. It looks to be when trying to create the new RosNode, I'm unsure if Meteor is able to connect to ROS Master successfully, I have confirmed local host and the port (http://localhost:11311) , I have put the exit output below.

I wonder if you have any ideas on this at all?

Thanks again, much appreciated.

hm, that's strange. It's possible that this is due to Meteor 1.8, I haven't tried that. But this works fine on meteor 1.6. I'm assuming you are on kinetic (ubuntu 16.04)?
